Application filed January 6, 1930. Serial No. 418,717.

This invention relates to a storm sash especially designed and adaptedfor use with metal window frames.

One of the principal objects of the present invention is to provide a storm sash which may be readily and easily attached to a metal window frame and which while of light weight construction is strong and rigid whereby racking or distortion of the storm sash is avoided.

Another object of the invention is to provide a storm sash of this character which is of simple construction and adapted to be manufactured easily and at a comparatively slight expense.

Other objects and advantages reside incertain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claim, reference being had to the accompanying drawings forming a part of this specification, and in which:

Figure 1 is a view in elevation showing a storm sash embodying the present invention attached to a metal window;

Figure 2 is a view of the storm sash in rear elevation and showing the same detached;

Figure 3 is a View in transverse section taken on line 8-3 of Figure 1;

Figure 4 is a view in longitudinal section taken on line 4.-4 of Figure 2;

Figures 5 and 6 are fragmentary detail views taken on lines 55 and 6-6, respectively, of Figure 1; and

Figure 7 is a detail sectional view taken on line 77 of Figure 4:;

Referring to the drawings, the numeral 1 designates generally a metal window frame which is provided with a main sash frame 2. The construction of this metal window frame per se forms no part of this invention but for a full disclosure of the window and main'sash frame constructions reference is window structure, filed July 1, 1929, Serial No. 374,994.

For the purpose of the present invention an outwardly directed edge flange 11 and a crimp or channel 12 around its inner margin, each crimp or channel having an inwardly directed edge flange 13. In addition, there are integral cross members constituted by flanged channels or crimps 14 (see Figures 1, 4 and 6), which brace and stifl'en the side members 6 and 7 and which provide channels or sockets for the reception of doubled mullion strips 16, the ends of which have integral attaching ears 17 spot welded to the side frame members 6 and 7.

The flanges 13 of the inner marginal channels or crimps 12 and the flanges of the crossed channels 1 1 aflord seats to which glazing G is applied by putty P and clips C.

This structure provides a storm sash which is stiff, strong and rigid and yet of very light weight. Theoutwardly directed flanges 11 of the frame members 6, 7, 8 and 9 are adapted to fit flatly or flush against the inwardly directed flanges of the window frame. Moreover, these flanges 11 are provided with threaded openings which carry attaching screws 20. The flanges 3 of the window frame have similar threaded openings 22 which register with the openings 21 and flanges 11 when the storm sash is assembled with a window frame. This permits the screws 20 to be engaged with the threaded openings of the window frame and thereby releasably fasten the storm sash into position.

The invention claimed is A storm sash for use with metal window 5 frames and comprising a storm sash frame including side frame members and end frame members constructed of a. single piece of metal and having integral outwardly directed marginal flanges designed to stiffen the storm 19 sash frame and to provide attaching and v substantially weather tight engaging ,mem bers adapted 'tocoo perate 'with'th'e frame of the Window and releasable fastening means for securing the flanges properly engaged with the frame of the window.

In witness whereof'l'hereto 'aflix my signa- I t-ure. v.
